Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO supplies 7-(1,3-Dimethyl-1h-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (CAS 1002243-77-7), a certified reference material (molecular formula C12H10N6, MW 238.25 g/mol) for analytical method development and quality control.
Structurally, 7-(1,3-Dimethyl-1h-pyrazol-4-yl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile (C12H10N6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 238.25 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
